Abstract

A road vehicle with a vehicle frame and a rear axle connected to the vehicle frame is provided with an ambient air purification device with filter elements for removing dust, particulate matter, and gases from ambient air. The ambient air purification device is arranged transverse to a longitudinal vehicle axis in an exterior region of the road vehicle at a vehicle rear of the road vehicle in an underfloor region such that at least the filter elements are arranged behind the rear axle of the road vehicle in a travel direction of the road vehicle. The ambient air purification device is received in an installation space of the vehicle frame. The ambient air purification device is flowed through in longitudinal vehicle direction. A free outflow zone of the ambient air purification device is arranged, in travel direction of the road vehicle, behind the ambient air purification device.
